How do I install this on a Mac? Can I boot from the .iso image provided online- it looks to be windows specific. Update- I burned the ISO to a DVD and attempted to boot. All I got was a blank screen with a blinking DOS cursor and no disk activity. I'm on OS X 10.12.4.

To be honest, I'd say such a small difference was within the margin of error of drive benchmarking. Which is far, far from an exact science. Especially if the drive is a system disk and is handling all the OS work and your background programs.

Also, are you comparing from immediately before the update, after the drive was used and dirtied up some? Or from a benchmark you took when the drive was shiny and new?

Ok update Disable hardware bitlocker on your drives before you do this update. I had to remove power from my pc before they were useable again (all of them showed bitlocker raw) and on one that did not even work...becaue on that drive i tried to reformat it while it was in that state and it became write protected (less than 3 weeks old by the way) for a while. But after about an hour it started to work again.
